This is an update i'm sharing two weeks late. Leen Ammeraal released it on 12th of September actually. Let's blame the delay on the job duties, a sweaty sweet trouble which pays me for the time.
Version 1.83: Illegal moves sometimes occurred when the chosen level was 0s per move for the computer. Again, this was reported by Mr. Bakkouz. In this new version such illegal moves should no longer occur.
